The group’s agency, AYIN Holdings, revealed the meaning of the name HALO (short for ‘Hexagon of Absolute Light and Organization’): “The name of rookie boy group HALO uses the dictionary meaning of the word to represent an idol group that always shines bright everywhere they go when all six members come together.”

Dino is the team’s oldest as well as the main vocal, who trained for a very long time before debut. Yoon Dong is the group’s youngest, born in 1985, and the rapper of the team.
